Attorney General Eric Schneiderman, who took office at the beginning of the year, announced today his office will “undertake a thorough review” of AT&T’s proposed $39 billion takeover of mobile phone company T-Mobile.

The mega merger already is sure to get a careful look from federal regulators concerned about whether a combined AT&T and T-Mobile will be powerful enough to squash rivals and jack up consumer prices for mobile services.

Schneiderman said in a statement that the Attorney General’s office will assess the anti-competitive impacts on consumers and businesses in the state of New York. He made a point of the mentioning the possible impact on people in Rochester, Albany, Buffalo and Syracuse — where his office says consumers have limited options for wireless carriers.
